(There's a man dead on the floor of a freezer. Nick and Sara stand over the body looking down at him.)
Nick: Frozen stiff.

Catherine: This isn't a costume. It's a six-foot condom.

Robbins: The last time this happened they tried to chop the guy out. 1989-- year The Mirage opened.
Nick: How'd it go?
Robbins: Lost an arm and a leg. I miss the cold weather.

Wwarrick: If I had to walk around dressed like Rocky Raccoon, I'd be drinking, too. I don't get this whole thing.
Catherine: Oh, hey, Warrick, it's Vegas. People come here to be animals.

Catherine: Hello, Sexy.

Catherine: Okay, well ... I've heard of some guys getting off in some weird ways, but humping an animal suit? Well, whatever happened to normal sex?
Grissom: What is normal sex?
Catherine: Uh, you think it's natural for a grown human to only be intimate with a talking animal?
Grissom: Well, Freud said that the only unnatural sexual behavior was to have none at all. And after that, it's just a question of opportunity and preference. And evidently, many prefer the feel of fur to the texture of human skin.
Catherine: Well, I like hairy chests, but I'm not about to bop a six-foot weasel.

Brass: Are you buying this guy?
Catherine: Oh, who the hell knows what goes on in a furpile?

Grissom: Well, you know, pheromones are the basis for mammalian reproduction. When the female is in estrus, the male picks up on her come-get-me scent. But most mammals only copulate seasonally.
Catherine: How boring.

Catherine: You know, if a couple has any kind of history together, they know how to press each other's buttons.

Grissom: Whoa. This is incredibly detailed. Eyelashes, nostrils ...
Catherine: Oh, yeah. That's what you see out of. I once dated the Detroit Lions Mascot. Off-season. Dutch was his name.
Grissom: The breadth of your social experience never ceases to impress me.
(Catherine smiles. Grissom takes photos of the body.)
(Catherine takes something out of the mouth of the mask. It's a piece of blue-colored yarn.)
Catherine: Dutch never had furballs, though.

Grissom: I'm not so sure that people who dress up like cuddly forest creatures
carry guns.
Catherine: You don't think they allow plushies in the NRA? All right, then who
shot him?
Grissom: Well, we have a grassy knoll ... but no Lee Harvey Oswald.

Sara: (to Nick) Okay, I will bet you a double-double animal style that one of them employs a guy with a blue 1984 Monte Carlo.

Sara is supposed to be a vegitarian. This is the second episode where she mentions eating meat after throwing a hissy fit to Grissom over her being a vegitarian.

Episode Title: Fur and Loathing

The episode title comes from the novel Fear and Loathing in Las Vegas: A Savage Journey to the Heart of the American Dream by Hunter S. Thompson.

Warrick: If I had to walk around dressed like Rocky Raccoon, I'd be drinking, too. I don't get this whole thing.

Rocky Raccoon is the partner of Bullwinkle the Moose from The Rocky and Bullwinkle Show.

Nick: Well, Lone Ranger had Tonto. Some Doofus has George.

Refers to the 1950s series The Lone Ranger

Brass: Well, he gives us all the furnames of people in the pile. What are we going to do -- put out an APB on Tom and Jerry?

Tom and Jerry are a cat and mouse cartoon duo originally produced by MGM.

Wolf: Password, please?
Catherine: E-I-E-I-O?

"E-I-E-I-O" is part of the chorus of the children's song Old McDonald Had a Farm.

Catherine: Ooh! These costumes are pretty marinated. Smokey could've used some deodorant.

Smokey is Smokey the Bear. He was part of an advertising campaign in the 70s and 80s to encourage the prevention of forest fires.

Grissom: So I guess we're looking for a wolf ... in wolf's clothing.

A twist on the fairy tale reference to a wolf in sheep's clothing.

Grissom: Well, we have a grassy knoll ... but no Lee Harvey Oswald.

Lee Harvey Oswald either shot President Kennedy or was framed for his assassination depending on your point of view. One conspiracy theory says there was a second shooter on a grassy knoll.

Sam Vega: You're a triple threat -- robbery, kidnapping, murder. Big & best foods, Al Sesto, George Bartell. Any of this resonate?

A triple threat is a phrase usually used to define performers who act, sing and dance.
